IMPROVEMENT IN ROAD-SCRAPERSQ Specification forming part of LettersPatent No. 193,297, dated July 17, 1877 application filed J une 23,1877.

To all whom it may coacern:

Be it known that we, URIAH THOMPSON and L. LAROY THOMPSON, ofOardington, in

the county of Morrow and State of Ohio, have invented certain new anduseful Improvements in Road-Scrapers; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pervtains tomake and useit, reference being had to the accompanying drawings, whichform part of this specification.

Our invention relates to an improvement in road-scrapers; and itconsists in the arrangement and combination of devices that will be morefully described hereinafter, whereby a cheap, efiicient, and easilmanaged machine is produced for scraping roads, cleaning out ditches,and all other such purposes.

The accompanying drawings represent our invention.

a represents the axle, b the two drivingwheels, and a the tongue.Branching out from each side of the tongue near its rear end is thebrace or support d, upon which is placed the platform 0 for the driverto ride upon. Upon the top of this platform are secured the two bracesf, which extend diagonally backward toward the wheels, and have theirrear ends securely fastened upon the top of the axle by means of theeyebolts g, which pass down through them and through the rear ends ofthe braces d. Olamped or otherwise fastened to the under sides of therear ends of the braces d are the metal plates h, which have eyeholesthrough their rear ends. Hooked into the eyes on top of the bolts g, andinto the eyes of the metal plates h, are the four draft-rods i, whichhave their rear ends attached to the scraper. The scraper consists ofthe two vertical rods Z, wide board a, se-

cured at their front sides, and the metal plate 0, secured to the loweredge of the board in the usual manner, the two upper draftrods, havingtheir rear ends hooked into eyebolts which pass directly through the topof the two rods, while the two lower draft-rods have their rear endshooked into similar eyebolts which pass thronghboth the rods and theboard. Through the board and the vertical rods 1 are made two or moreholes, so that this board can be adjusted up and down to suit thedifferentkinds of work that may be required of it.

Extending upward from the axle and the rear end of the tongue are thetwo standards 1', upon which is pivoted the operating lever s, which hasits rear end connected to the scraper by means of the rods 10. Thedriver, standing or sitting on the platform, can raise or lower thescraper at will. After the work is finished, or in going to or returningfrom the work, by depressing the front end of this lever so as to catchunder the hook e on the front edge of the platform, the scraper will beraised high above the ground and drawn inward close behind the axle, soas to assume the position'shown in the drawings. All of the rods bywhich the scraper is attached to the sulky-frame having universaljoints, the scraper can be adjusted to any desired position, and thusadapted to any kind of work that may be required. For leveling roads,scraping out ditches, and all other such work, our machine is effieientand readily managed, while being cheap and simple in construction.

Having thus described our invention, we claim- In a road-scraper, thecombination of the draft-rods i, axle a, vertical rods Z, scraper o a,lover s, and connecting-rod 10, all constructed and arranged foroperation, substantially as shown and described.

In testimony that we claim the foregoing we have hereunto set our handsthis 15th day of June, 1877.
